To all whom it may concern.'

Be it known that I, FRITZ WoLFENs- BERGER, engineer, a citizen ofSwitzerland, residing at Mlheim-on-the-Rhine, Deutzerstrasse, Germany,have invented certain new and useful Improvements in Devices for theSupport of Work; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a device for the support of work and has forits object to enable a piece of work to be fixed on a table and when-sofixed to -be adjusted so that various surfaces can be operated upon bydifferent tools Without the work having to be refixed on the table. Ithas previously been proposed to provide a table or plate to which workcan be fixed this work being rotatable about an axis so that thedifferent faces of the work can be presented to the same or differenttools. Such arrangements however had limitations since it was notpossible without refixing the work to operate on all the surfacesrequired but only those which were parallel to the axis of rotation. j

According to this invention the table to which the work is fixed is somounted that the work is rotatable in two planes at right angles to eachother.

Two constructions of the device according to this invention areillustrated by way of example in the accompanying drawings in which,

Figure 1 is a longitudinal section through such a device having twotables or plates on which Work can be fixed. Fig. 2 is a cross sectionthrough a modified construction having five .tables for carrying work.

In the construction illustrated in Fig. 1 the two vertical standards a acarry bearings in which is rotatably mounted a horizontal member b whichmay be in the form of a spindle. The latter is bored about its center atright angles to its axis to receive a spindle c on the ends of which arekeyed the tables d d. Each of these plates has indentations notches orlike divisions with which can engage the spring controlled bolt e sothat the position of the table can be set by rotating it about its axis.A disk f is mounted on the spindle t and provided with notches, recessesor the like for the engagement of a spring bolt g mounted on thestandard -a/ This enables the spindle to be set after rotation.

After the spindle has been adjusted and the plate d also set the spindleis fixed by the screw clamp h and the table by the screw clamp h.

In the modification illustrated in Fig. 2 a plurality of bearings areprovided on the spindle or member b and each table has a separatespindle which rests in the corresponding bearings. The circumference ofeach tablel may be provided. if desired with divisions with whichengages a spring catch. In either of these constructions the severalpieces of work on the respective tables practically balance themselvesabout the main spindle since the tables are symmetrically distributedabout this spindle.

Thisdevice vmakes it possible for example to bore, punch, lit and finishall surfaces of a iece of work without refixing it on the table.

successively treated by the same tool without adjustment of the tool andthus time is economized.

The device is particularly adapted for use as a boring or drillingltable where the operation to be performed on the work occupies a smallamount of time compared to that ordinarily required for fixing the workin position.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed I declare thatwhat I claim is I:

A work holding device comprising a rotatable spindle, means forsetting and retaining said spindle at any point in its rotation, aplurality of flat rotatable tables mounted on said spindle adapted tosupport the work to present the various faces thereof to the operatingtools, the axes of rotation of the spindle The standards may beadjustable on the It also enables several pieces of work to be and ofthe tables being located at substanstantally at right angles to eachother, and i0 tially right angles to each other, and means separatemeans for looking said tables to the for setting and retaining' thetables at any shaft and the shaft to its support.
